Description
Tone Script of the disconnect tone to
detect. The ATA device supports two
frequency components. If the tone has
only one frequency, use the same value
for both frequencies.
Each cadence segment must have the
same frequency.
The level value is the threshold to detect
each tone.
The total duration is the minimum duration
of the tone to be recognized as the
disconnect tone
If yes, the ATA device interprets polarity
reversal as a disconnect signal.
On an inbound PSTN call, ATA device
disconnects on the first polarity reversal.
On an outbound PSTN call, ATA device
disconnects on the second polarity
reversal (because the first polarity
reversal indicates the outbound call is
connected).
If yes, the ATA device interprets the
disconnect tone as specified in the
Disconnect Tone parameter as the
disconnect signal.
This is the signal energy threshold. Below
this threshold is considered silence.
